Effects of Pollution on Human Health

Effects of pollution on Human Health is extremely alarming. There are many diseases that can bring about a host of potentially fatal illnesses. From chronic bronchitis to lung cancer, air pollution has the potential to raise the risk of illness.

Air pollution and its link to the respiratory system is quite obvious. However, air pollution is also known to affect the circulatory system and the nervous system. When particular matter enters the nasal cavity, the lining ger irritated and the body may mistake it for an infection, This causes an inflammatory response, which can result in the exacerbation of any pre-existing conditions.


What Are the Consequences of Pollution on Human Health

  • Human health is also severely affected by particulates in the atmosphere. The particulates can cause nasal irritation and swelling. It can also cause a running nose.

  • Air pollution is additionally linked to lung damage and limited lung function

  • Air pollution can also have an inflammatory effect on the heart – it can elevate blood pressure and aggravate pre-existing conditions of the heart.

  • The risk of death significantly increases with long term exposure to polluted air. For instance, people susceptible to heart diseases are at higher risk.

Most Causes of pollution are often mainly attributed to anthropogenic causes. This means humans are liable for causing pollution. Water pollution is often defined because of the introduction of pollutants into a body of water. These can cause detrimental effects on the organisms that live in the water body or interact with the water. However, the causes of pollution can occur from natural processes or phenomena too.


Causes of Water Pollution – Anthropological and Natural

Water is able to dissolve many substances, hence it is called the universal solvent. This is an equivalent reason why pollution occurs easily. Following are the causes of water pollution:

Sewage and Wastewater

Many people put their waste directly into water bodies. Moreover, households may use septic tanks, which eventually infiltrates into the soil, causing pollution of groundwater which are not served by municipal treatment plants. 


Industrial Effluents and Industrial Usage

Some industries may directly pump their untreated wastes into water bodies like rivers. Moreover, various industries also use water as a coolant, thereby causing pollution . Increased water temperatures can cause a reduction in the levels of oxygen; which can cause the death of fish and other organisms.


Eutrophication

Eutrophication is caused when large quantities of nutrients are introduced into a body of water, causing the rapid growth of algae. This can decrease the oxygen level within the water, rendering the fish unable to breathe. Moreover, this phenomenon also can introduce dangerous toxins into the water body, which may harm or kill most organisms, including humans


Deforestation

Deforestation can cause soil erosion. When these loose soil particles enter a water body, they will make the water murky. This can make the water very misty as it also has the capability to cause mechanical damage to aquatic organisms, (such as sand particles getting stuck in gills).


Agricultural Run-Offs

Agricultural run-offs include fertilizers and other chemicals which will make the water toxic. Moreover, some of these fertilizers can induce eutrophication.


Accidents

Accidents can involve events such as leaks and oil spills. Oil spills, in particular, are very damaging to the environment and aquatic life. It occurs when large oil tankers, barges or drilling rigs are involved in accidents. The most well-known oil spill was that of the trouble Horizon, which occurred on 20th April 2010.
